Light bulb sign / Door handle

Light bulb sign
Light bulb sign

We often forget to turn the lights out before closing the door.
Precious energy is wasted by forgetting to turn off the lights on a vacant room.
This is a mistake that everyone has done.
You can acknowledge whether the lights are on/off even if the door is closed.
The door knob is perforated in shape of the bulb.
Light emerges from the hole,bulb-shaped.
Check the status of the other side of the door with the light leaking through "bulb like" opening.
With this opening, we can save leaking energy.
